ELAPSED-TIIVIE INDICATOR.

Application led January 3, 1916. Serial No. 69,882.

to improvements in charts or computing de` vices 'for indicating the elapsed time for return premiums on fire insurance policies, whereby to do away with certain disadvantages present in these devices as now used.

The main objections to the devices now in use are the extreme length of the charts necessary to permit the indication of elapsed time up to one year and the unnecessary length of the indicating member itself which, ,as a slide, must in most instances be extended-some distance beyon the chart itself.

The primary object of my invention is, therefore, to provide a double chart together with an endless flexible indicating member which need not at any time extend beyond vthe edges of the chart and which has its indicating month data arranged in novel and convenlent form to coperate with the chart itself, thus` obviating the above disadvantages and promoting other advantages to be hereinafter mentioned.

In the accompanying drawings illustrating my invention,' and forming a part of this specification Figure 1 is a plan View of a part of my improved chart including the indicating member. Fig. 2 is an enlarged section taken throu h the device longitudinally of one end o the indicating member and substantially on line 2-2- of Fig. y1. Fig. Sis a sectional View taken through the entire device, longitudinally of the indicating member. Fig. 4 is a. detail section taken through the device transversely of the indicating member and substantially on line 3 3 of Fig. 1, and Fig. 5 is a partial section taken as in Fig. 4, and illustrating a slightly modified form of construction.

Referring now to these figures, A inidi# cates the main body of the chart itself which may be formed of any material suitablefor the purpose and which is-preferably pro-4 vided upon at least one face, with a figure sheet A and which, as seen in Fig. 1, is divided into one hundred and eighty-two transverse columns and into longitudinal columns of numeral values, the latter being arranged in series of which one series is headed as best seen in the ligure last mentioned, in tensof dollars, another series in dollar units, and still another series into cents in multiples of five. It will `also be noted by reference to Fig. 1, that the sheet A is provided with spaced longitudinal 'number columns A2 and A3, the numbers therein increasing from 1 to- 182 in the column A2 and from 183. to 364 in the column A3, the numbers being within the transverse columns above mentioned.

In the space between the number columns A2 and A3, is arranged the upper run of an endless flexible indicating member B, the lower run ofwhich travels across the lower surface of the chart A and the ends-of which travel around rollers C, mounted in conformable recesses in the relatively opposite edges of the chart A between the number columns A2 and A3 of itssheet A', it being noted that this indicating member or belt B is proyided along its opposite edges at points immediately adjacent the number columns A2 and A3, with spaced columns in which are arranged in successive order the` numbered days of succeeding months during a year, each column being preferably composed of eighteen successive months in order that with the months of the two columns opposite to one another preceding each other by six months', any given number of days between any two'periods of a complete' vear may 'be indicated upon the face of the chart.

The indicating belt B may be provided with buttons or handles B at spaced points as shown in Figs. 1 and 2, or, as also shown in Fig. 1`, the shaft C of the roller C may be extended laterally beyond one edge of the chart A and provided with knobs C2 by which the belt may be turned as desired. Furthermore, as seen by reference to Figs. 4 and 5, the belt Bl may either travel upon the surface of the sheet A as in the former ligure, or may travel upon the face of the chart body A as ,seen in Fig. 5, between spaced portions of the sheet A. As before stated the belt B preferably contains in each of its side columns eighteen successive f Sucks in the enga-f the tea and this may be done by means-of rollers D at the rear 'of the chart as shown in F ig. 3. However, the l chart itself may be lengthened so asto ob.-

. viate the necessity of take up rollers of this nature. In any event it willbe seen that the 'arrangement I propose enables another chart -sheet vvA-2 .as shown in Fig. 2 to be placed uponthe rear face of the chart body A, this latter ychart sheet being where employed, designed for 4use with different sety of numeral values ory in computingshortv rate return premiumsl in the" vsame way that proifmta return premlums' are computed .upon

the obverse side of thechart, as will no'w be y 'de scribed.` lWith Athe device as,l thus described, pro rata return premiums may -be readilyindicated by moving the belt B so that the lparticular day of. thetparticular 'month upon which the insurance is `canceled is immediately above the numeral 1 in the number column A2 of the chart sheet v4A. Thus, supposing the day of cancella-- .'.tion to be December 15 upon'a policy `run-u- I- v the transverse column in which the numeral.

35,72 is arranged at the right hand side of theV chart, the amount to be returned will appear in the value lcolumns arranged in the series as above described. -Thus also, referring to Fig; 1, if thedate vof cancellation is Novem- 40 `ber 30, with the policy'to run until May 10 vof the succeeding year, the belt is placed as l show-n jand 'it will be seen that the 10th of May'in the lright hand column of the belt is opposite the numeral 161 in the number column A2 vof the vlchart and opposite the `amount $4.41 which would be the return value if the premium ofthe policy is $10.00. Likewise, should the day of cancellation be the same and the vpolicy to run until Novemf ber 28 ofthe succeedingyear, it will be seen from Fig. 1 that the parts'properly placed bring the 28th of November in the left/hand column of the belt yB opposite -vthevnumeral u from one hundred and eighty-three tothree ing siX months in advance o one another,

.363, in thenumber column A3 of the-chart sheet A and opposite the amount $9.94 55.

which would be the return value upon a policy, thepremiumof which is $10.00.

It-will thus be seen that I provide a .computing chart of this` nature'which, though `of minimum` size and much smaller and more readily utilized than those now in use, may indicate with but a single movement of the indicating. web, elapsed time within an entire year, and which is capable of convenient use without the extension `of any portion of the indicating member beyondthe limits of the lchartsheet itself, o r stand in the way of either the'user or passers-by.

l. A double. chart of the character described having spaced number columns, in

` one of which the numerals progressxfrom one to one-hundred and eighty-two .and .in v the other of which the. numerals progress hundred and sixty-four, and an endless shiftable Vindicating member .movable lin the space between said lnumber columns and having spaced longitudinal -columns for successive months and days thereof, of which any par. ticular day may beregistered with any o f the numerals ofy the said number columns, and the opposing months of the two days columns of the said indicatin member befor `the, purpose described.

2. A chart of the characterjdesc'ribed'having spaced number columns, in one of which y the numerals progress from one to one-hun-l y dred and eighty-two and in the other of which the numerals progress from one hundred and eighty-three to three-hundred and sixty-four, and an endless'shiftable indicating belt mounted around the chart to travel.

longitudinally 4in the vspace between said 95 number columns and having along its opposite edges day columns for successive months thebelt being shiftable within the limits of the chart to register anydesired day with any ofthe numerals of the said number columns, and the opposing months of the two columns `of said indicating belt being six lmonths in advanceof one another, all for the purpose described.
